HOSE-COUPLING.

Specification of Letters Patent. Patented A1313 2? 1916.

Application filed December 22, 1914. Serial No. 878,575.

To all whom it may concern Be'it known that I, ROBERT BENNETT, a citizenof the United States, residing at Beacon, in the county of Dutchess andState of New York, have invented new and useful Improvements inHose-Couplings, of which the following is a specification.

This invention is an improved'hose coupling, especially adapted for usein coupling lengths of fire hose together, the object of the inventionbeing to provide an improved hose coupling, which is cheap and simple inconstruction, which may be readily coupled and uncoupled, which iswatertight and which is enabled to sustain extreme water pressure sothat the lengths of hose will remain coupled even when the nozzle isshut off. The invention consists in theconstruction, combination andarrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a longitudinal sectional Viewof a coupling constructed in accordance with my invention, showing thecoupling members in coupled relation. Fig. 2 is a transverse sectionalview of the same on the plane indicated by the line a,a of Fig. 1. Fig.3 is partly an elevation and partly a longitudinal sectional view of oneof the coupling Fig. 4 is a similar view of the other coupling member.

My improved hose coupling comprises a pair of tubular members 1-2 whichcorrespond in exterior diameter. These members are threaded on theirinner sides at their outer ends as at 3 to enable the hose sections tobe fastened thereto by the usual means and in the usual manner. Themember 1 has a diametrically reduced projecting annular portion 4,forming an annular shoulder 5 at its base, the said projecting portionbeing tapered or beveled on its outer side at its outer end as at 6. Thesaid member 1 is provided with exteriorly arranged lugs 7 for engagementby a spanner wrench and its reduced and extended portion 4 is providedat diametrically opposite points with radial studs 8. The member 2 iscounterbored at its outer end at 9 to receive the projecting portion 4of the member 1 and has an annular shoulder 10 at the inner end or baseof said counter-bore. The said member 1 is also provided with curvedslots 11, which are here shown as quadrant shaped and which are adaptedto receive the studs 8 of the member 1 so that by inserting said studsin said slots and then partly turning one member the said studs coactwith the slots to tightly and securely draw the members 12 together andhold them in coupled relation. To effect a watertight joint between themembers 1-2 I also provide a gasket 12. This gasket is fitted in thebase of the counterbore 5 of the member 2 and has a wall 13 which bearsbetween the wall of said counterbore and the beveled or tapered portion6 of theprojection 4, the said wall 13 being beveled on its inner sideto correspond with the bevel of said projection. The said gasket is alsoprovided with a base wall 14 which is at right angles to its wall 13 andwhich bears between-the end of the projection 4 and the shoulder 10.WVhen the members 12 are coupled together the said gasket is compressedso that it efiects a perfectly watertight joint between the said membersas will be understood. The gasket is provided on the outer side of itswall 13 with a flange or bead 15 which fits in a corresponding groove 16in the member 1 and also has a bead or flange 17 at its base which fitsin a corresponding groove 18 in the shoulder 10. These grooves andflanges securely hold the gasket in place and prevent it from beingdetached from the member 2 when the members of the hose coupling aredisconnected from each other. The member 2 also has lugs 19 forengagement by a spanner wrench the spanner wrench being used inconnecting and disconnecting the coupling members.

Having thus described -my invention, I claim In a hose coupling, thecombination of a member having a tapered projecting end and alsoprovided with radial studs, and a-second member having a counter bore toreceive the tapered end of the first named member and also having aquadrant shaped locking slot to receive the studs of the first namedmember, and a gasket in the base of the counter bore of the second,named member for ensaid rib and grooves co-acting with each gagement andcompression by the tapered other to prevent detachment of the gasket.1;)
